Business Machines Corpora- N. Y., a `corporation of New Application october 11, 1934, serial No. 747,890 14 claims. (01.'164-113) The present invention is directed to improvements in card punching machines.

In card punching machines it is common practice to provide skip bars for causing certain fields of the cards to be skipped when punching is not desired in such fields. Mechanisms for performing such functions are well known in the art.

Bars of a type known as a high bar have usually been provided with suitable means in the first card column position which will cause the carriage to be skipped from such position to a column of another field for numeral punching thereon. It is frequently desirable to have nevertheless, certain cards punched in the first card column position and the present machine provides a simplied structure for preventing the effective action of the skipping mechanism and thus causing the carriage to be retained in the first column position. By the selection of either of two distinct manual means the skip mechanism will be effective or not, dependent upon the manual means selected to return the carriage.

The main obect of the present invention is to provide a sele tive means for causing the skipping mechanism to be effective upon the first card column position of the carriage, or not, as is desired by the operator.

A still further object is the provision of two distinct manual means for selecting the desired operation. n

A still further object of the invention is to cause by one of the manual means used for returning the carriage the skipping of the carriage to the first selected field, when it is returned to the first card column position.

Various other objects and advantages of the invention will be obvious from the following particular description of one form of mechanism embodying the invention and from an inspection of the accompanying drawings; and the invention also constitutes certain novel features of construction and combination of parts hereinafter set forth and claimed. p

As more fully describedin the patent to F. L.

Lee, et al., No. 1,772,186, dated August 5, 1930 the 10 machine is provided with a handle 2 (Fig. 1), having a normal position at the right hand end of the machine and being mounted for leftward movement along the side of the machine. Whenever the handle 2 is moved to the left it is ar- 15 ranged to shift a rack 3 in the same direction and by means of a picker I carried by rack 3 a statistical card is withdrawn from the bottom of a pack in a magazine 5 and advanced to be operated on by a punching mechanism I. An escapement rack 6is provided with teeth 6a (Fig. 2) at itslower side to mesh with a. gear 1 and the rack 3 meshes with a gear 8, (Fig. 3) both gears being mounted on a cross shaft 9. The escapement rack 6 carries a pusher III (Fig. 2) 25 and a guide 1I which convey the card step-bystep past the punching mechanism I.

Due to the gear connection 1, 8, the movementof the handle 2 and picker 4 to the left is accompanied by a movement to the right of pusher I0 and this act'on will deliver a card from the magazine 5 to first column punching position; after which pusher IIJ will further advance it step-by-step to pass the punching generally designated I 2 in Fig. 3 permits the independent return of the rack bar 3, picker 4, and handle 2 to the right to normal position. The rack 3 meshes with a gear I3 (Fig. 3) secured to a. shaft I4 and to said shaft there is connected one end of a coil spring mounted in a spring barrel not shown herein but shown in detail in Fig. 30 in the aforesaid Patent No. 1,772,186. The one way clutch I2 permits the coil spring to return handle 2 and parts movable therewith independent of any movement of the carriage carrying'pusher I0 and guide II. y

Escapement mechanism- As more fully explained in the Patents Nos. 1,772,186 and 1,914,263 the depression of any punch key I6 (Fig. 2) is adapted to select and to cause depression of a related interposer I1 which will rock a bail I8 and a shaft I9 connected `thereto to render the escapement mechanism effective and the escapement rack 8 and the card carriage will advance one tooth to permit punching in the next column of the card. v Shaft I9 v(l"ig.'5) has secured at one end oppositely extending' arms 20 and 2|- of which 20 is provided with a laterally'extending pin 22 vfor engagement with an enlargedopening 23 in` a stepping dog 24 which is loosely pivoted on the rod I9.l The opposite arm 2| is'provided with 'a pin 25 extending in a slot formed in the locking dog 26 between its pivot and its'engaging end.

When rod I9 is rocked the arm 20' will through,

pin 22 lift the stepping dog 24 out of one of the notches in the escapement rack 6 and at the same time arm 2| will depress locking dog 25 into a notch between the rack teeth. At this time a spring 21a advances the loosely pivoted dog 24 a short distance but' sumcient to permit this dog to move above the top of the next tooth when the locking dog is again raised. The stepping dog 24, due to the movement of rack 6', will ride down the next tcoth until it strikes the end thereof and the carriage is arrested. The 4usual spring drum (not shown) is provided to,bias the rack 6 toward the left as viewed in F18. 5.

the Schaai Patent No. 1,426,223 and comprisesa skip bar 21 removably mounted on escapement rack 6 and is provided with a seriesV of notches 28 and cam surfaces located at the fields where the carrier is to stop for the punching operation. The skip lifter is indicated by numeral 29. 'Ihis skip lifter is provided with a hole 30 at its inner end adapted to engage a pin 3| and rest on a colar 32 secured to the pin. This pin 3| vextends through a' hole 33 in a toggle link 34 and into a pivoted T-bar 35. The pin is riveted in the T-ba-r. A pin 36 extends through a hole 31 in the other end of the toggle link 34. The pin 36 is rst inserted in the upper bearing of a leaf spring 38, then through the toggle link and then into the lower -bearing of said leaf spring. This leaf springf38 is secured to the frame of the machine by means of a screw 39. The T-lever is provided with a slot 4|| which enga-ges over a pin 4|. The leaf spring pressing on the toggle link tends to buckle the toggle one way or the other and the stop pin 4| engages one wall of the slot 40 or the other and limits themovement of the toggle lever. It will readily be seen that the skip lifter 29 will therefore be held in its retracted position -where it is inoperative to in any way affect the regular escapement feed of the carriage, or held in its extended -position where it becomes effective to modify theaction of the escapement. The end of the skip lifter is held on the pin 3| by a plate 43.

Skip bars 21 are usually manufactured with a notch in the rst column position. This notch is indicated by numeral 45 and comprises a cam edge, and a straight edge parallel to the longitudinal edges of the skip bar 21. It is desirable at times that punching be permitted in this first card column and at other times that the carriage be automatically skipped beyond this position ,of the T-bar 55.

curved finger 5I engaging a circular extension r Rocking of the lever 49 will operate the toggle mechanism to shift the skip lifter 29.-

The skip bar 21 is latched in position by means 5 capement rack 9, skip bar 21, extension bar 5 are all carried by the carriage when the bar 54 15 is in the position shown in Fig. 'l the upper straight edge of the skip bar 21 is continued by a'straight edge of the bar 54 to thus fill thev notch 45. The lower camr surface 29a (Fig. 7), of the skip lifter coacts with the upper straight 20 edge of the bar 54 and by reason of the fact that the end of the vlifter 29 lies under the stepping dcg 24, (see Fig. 5) it will elevate the dog 24 to release the escapement rack 6 and the card carriage for movement. Thereupon the lifter arm 25 29 coacts with the next notch 25 in the bar 21 and dog 24 will interrupt further movement beyond such point.

Upon a subsequent depression of a numeral key by means more fully described in the patent 30 to Schaaf! 1,426,223 a member 58 is operated when any numeral punch keyf'is depressed and by rocking the T-lever 35 counterclockwise it will be automatically retracted. In the present construction such member may constitute an 3" arm 58 secured to the rock shaft I9, the end thereof being in the path of an extension 59 of the T-lever 35.

summarizing, when the carriage is returned by handle 2 to the first card column position the 40 movement of the carriage itself will automatically cause the skip lifter to be shifted and the -carriagePautoinatically -escaped to the nrst column of the next card field. The skip lifter is then automatically retracted when the first nu- 45 meral punch key is operated.

When it'is desired to punch in the first card column the carriage is returned by manual means other than the handle '2. The arm 56 is formed with .a finger piece 60 and obviously since it is mounted on the carriage it constitutes a manual means for shifting the carriage to the right, similar to the handle indicated by numeral |14 of the Patent No. 1,772,186.

When arm 58 is rocked, obviously the exten- 55 sion bar 54 is shifted to the left to align the skip lifter' with the notch 45 in the first card column positlon of the carriage. When arm 56 is rocked a lug 6I thereof strikes a bracket plate 6 52 secured to the carriage preventing further 0 manual movement of the finger piece 60 so that continued pressure on the same will cause the carriage to be shifted to the right.

fThe bar 41 will, as before, shift the skip lifter 29 but'the same will merely project through the 65 notch 45 without elevating the stepping dog 24 to release the card carriage. Upon depression of a numeral key for punching in the first card column the carriage will be shifted a step and 70 non without requiring mitm adjustment of arm "5" 66. To this end there is pivoted on the screw 51 a plate 63 provided with a nger piece 64 and a shoulder 65 normally abutting the lug 6I. Finger piece 64 ls first shifted to the right (Fig. 4) so that 'the shoulder 65 will rock the manual 56--60 to align the skip lifter 29 with the notch 45. The nger piece 64 can then be locked ln a notch 66 of a bracket plate 61 attached to the bracket 62 by a screw 68.

While there has been shown and described and pointed out the fundamental novel features of the invention as applied to a single modification, it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention.
